PROCESS 0F MARKING PAPER.

Application filed March 8, 1926. Serial No. 93,047.

This invention relates to a process for marking paper such as carbon or manifolding paper, and has as an object to provide a process which shall be simple and inexpensive of application, and which shall provide a clear and easily distinguished marking of pleasingappearance on the paper.

The paper stock which is ordinarily used in the making of carbon or manifolding paper, is usually of the grade known as tissue. This paper is coated on one side with carbon or vtransfer ink which penetrates to the opposite side, giving a different appearance thereto.

In a former Patent No. 1,513,246` issued October 28, 1924 to William J onse Hughes there was described a process for marking paper which comprised conditioning a certain area of the paper prior to the complete penetration of the transfer material or carbon ink therethrough, so that the area thus conditioned becomes more or less pervious to penetration by the transfer material, with the result that after the transfer material has been appliedand 'has penetrated, the conditioned areas will be visible on the uncoated face of the sheet in contrast with ythe other areas notso conditioned. vAccording to the present process the paper is marked with a fluid material such as a dye which penetrates the paper, but which may or may not affect the perviousness of the paper to the carbon or transfer ink. When the carbon or transfer ink has been applied, the completed mark exhibits the combined effects of the marking fluid and the carbon ink, presenting a soft and pleasing vappearance.

' As a specific example of a preferred method of carryingout the process of the present invention, a name or mark may be printed on one side of a sheet of paper, using as a marking fluid-a dye or other colored fluid which enetrates the'paper so that the name or mar will appear on the reverse side of the sheet. Thereafter transfer material or carbon ink may be a plied to the side of the sheet to which the e was previously applied and this material likewise enetrates the paper to a certain degree an changes the appearance of the reverse side of the sheet. The transfer material or carbon ink may also penetrate the area which has been previously marked with the dye and may blend `with the mark already produced, the

combination of the two resulting in a mark which is clear cut and easily distinguishable, but at the same time is soft and subdued giving somewhat the effect of a water mark.

The accompanying drawings illustrate the various steps of the process.

Figure 1 shows a fragment of the usual tissue paper used in making carbon or manifolding sheets.

`Figure 2 shows an identifying word printed upon the face of the sheet exposed to the reader in some penetrating marking fluid such as dye.

Figure 3 shows the reverse side of the sheet shown in Figure 2.

Figure 4 shows a coating of transfer material or carbon ink applied partially to cover the previous printing and upon the same side as the printing shown in Figure 2.

Figure 5 shows the reverse side of Figure 4, and

Figure 6 shows the completed sheet.

It is to be understood that the invention may be variously modified and embodied within the scope of the subjoined claims.

I claim as my invention 1. The process of marking carbon or manifolding paper which comprises applying penetrating marking fiuid to one side thereof, and then applying transfer material to the same side.

2. The process of marking carbon or manifolding paper which comprises applying penetrating marking fluid to one side there- 0f, and then applying penetrating transfer material to the same side and covering said marking Huid.

3. The proces-s of marking carbon or manifolding paper which comprises applying penetrating dye to one side thereof, and thzn applying transfer material to the same s1 e.

4. The process of marking carbon or manifolding paper which comprises treating a portion of saidl aper with a penetrating marking fluid, and) then treating the same portion of said paper with a. penetratingl transfer material.

5. The process of marking carbon or unooated side of the paper and modifying the appearance of said mark by the application of transfer material.

In testimony whereof, I have signed my name to this specification this '4th day of March, 1926.

WILLIAM JONSE HUGHES.
